A=6dm T=4dm B=80cm Luas trapesium tersebut= Pake cara

1 dm = 10 cm
80 cm = 80 : 10 = 8 dm

luas trapesium = 1/2 × (a + b) × t
= 1/2 × (6 + 8) × 4
= 1/2 × 14 × 4
= 28 dm^2
= 2800 cm^2

A = 6 dm = 60 cm
B = 80 cm
T = 4 dm = 40 cm

Ltrapesium = 1/2 x (a + b) x t
= 1/2 x (60 + 80) x 40
= 1/2 x 140 x 40
= 70 x 40
= 2800 cm2

Jadi, luas trapesium adalah 2800 cm2
